Are firewalls useful? and another thing...
If you ever feel in need of a lesson in humility, try reading through the TCP/IP RFCs and related literature. I have two questions I have no idea how to answer but rather naively expected that reading this material would help. It didn't, in truth because I didn't understand most of it; so now I'm asking you to explain the issues to me.
The two questions are, first, why can't router software let us stamp out address spoofing? And secondly, why do we use firewalls?
